The invention discloses a scraping resistance halogen-free flame retardant thermoplastic elastomer composition, which comprises the following ingredients in percentage by weight: 15 to 50 percent of poly-phenylate resin, 20 to 40 percent of styrene thermoplastic elastomers, 10 to 30 percent of solid halogen-free flame retardants, 0.5 to 5 percent of flame retardant synergists, 5 to 20 percent of plasticizers and 5 to 20 percent of scraping resistance agents. The halogen-free flame retardant thermoplastic elastomer composition provided by the invention has the advantages that polysiloxane is added into the halogen-free flame retardant thermoplastic elastomer composition in a polymer form, the excellent scraping resistance is realized, the original mechanical property, the flame retardant performance, the appearance and the soft hand feeling are not damaged, on the basis, the viscosity of the composition in the extruding processing process can also be reduced, the energy consumption is reduced, and better low-carbon and environment-protection effects can be realized.
